SHEET COUNTING AND INDICAT'ING APPARATUS.

Specification of Letters Patent.

Patented May 16, 1916.

Application filed March 18, 1915. Serial No. 15,188.

sheets are successively fed. Its more par-- ticular use is in connection with a stencilduplic ating'apparatus having a drum and pressure roller, which latter moves upwardly into printing position when a sheet is passed between the drum and pressure-roller, mechanism, however, being provided to prevent the pressure-roller from rising into its operative position when no sheet is positioned, in the regular operation of the machine, be-

tween the drum and roller. My improved attachment or device is intended to be mounted on such a machine and so connected as to count the sheets printed. In its operation a controlling member moves with the pressure-roller of the machine and serves to connect ordisconnect the registering device for operation. An actuating member is moved each operation of the ma-' chine and serves to advance the counting mechanism one unit each rotation of the drum provided that a sheet is in position to be printed upon, and accordingly the controlling device is in positipn to form a connection between the' actuating device and the counter-advancing means. When, however, no sheet is in position to be imprinted,

the controlling device is in such a position as to break the connection between the actuating and counter-advancing mechanisms, and accordingly the counter is not advanced.

In the operation for which this device is chiefly intended, the indicating means are set to indicate the number of sheets which it is desired to print. Upon the operation of th'e\ machine, the indicating pointer or pointers move in such direction past the dial of the predetermined number.

or dials of the device as to always indicate the number of'sheet's remaining unprinted Upon the completion of the desired number of printi1ig operations, suitable indication of this I fact is given, as by the striking of a bell, after whlch the counting and indicating members remain stationary, if the machine is further operated.

While my device is particularly intended for cooperation with a duplicating machine of the character mentioned, it is. adapted for cooperation with, and actuation by, other forms of mechanism, particularly those in which the presenceor absence of an article to be counted, or the like, in its expected position in the mechanism, should exert a control over the operation or non-operation of the counting, indicating and signaling devices.

The objects'of my invention accordingly are the provision of improved counting and indicating devices of the character referred to, andthe combination of the same with operating and controlling mechanisms, such as duplicating machines or other printing devices, in which the members of a printing couple move intooperative position when a sheet to be" printed and counted is positioned between the same, but not otherwise.

Other objects of my invention reside in the construction and combination of parts as will be hereinafter fully pointed out.

In order that a clearer understanding of my invention may be had, attention is hereby 'directed to the accompanying drawings forming part. of this application and illustion.

The drum 1 is provided with a cam 10 which depresses roller 6 each rotation of the drum, to move the pressure-roller 2 from its operative position.

awa

M eans are provided to prevent the rising.

of the pressure-roller into its operative position, when no sheet is fed forward between the drum and pressure-roller, since the pressure-roller should not be permitted to contact the stencil or printing surface ofthe drum. A suitable mechanism for preventing the upward movementof pressure-roller 2, when no sheet is positioned between the drum and pressure-roller is described and illustrated'in patent of Albert B. Dick, No. 1,140,883, dated May 25, 1915, stencil-duplicating machine, which patent describes a duplicating machine of a character adapted to co6perate with my counting and indicating mechanism. As is described in said patent, a series of feelers 11 are mounted on a rockshaft 12, feelers 11 being spring pressed into upper position and adapted .to extend through openings in aplate 13 over which sheets are successively fed. Sheet-forwarding devices are illustrated as comprising roller 14 and the sectors 15 adapted to coact therewith, the sectors being mounted on a shaft 16 which is continuously rotated Cir during the operation of the machine. A cam 17 on shaft 16 coacts with a roller car'- ried by arm 18 mounted on rock-shaft 12.-

'Feelers 11 move upwardly through the openings in feed plate 13, when permitted to do so by cam 17, when no sheet is positioned" between the sectors 15 and roller 14, the consequent rocking of rock-shaft 12 serving to actuate mechanism whereby roller 2 is prevented from rising into contact with drum -1. This .mechanism comprises a lever 102 pivoted onshaft 8, having one end contacting the upper bearing of pressure-roller 2 adjacent one end thereof and having its opposite end coacting with an automatic stop I mechanism, positioned by the rocking of rock-shaft 12, to prevent the upward movement of arms 3 and pressure-roller 2.

tween sectors 15 and roller 14, the feelers 11 cannot rise through the openings in plate 13, the roller on arm 18 is held away from the surface of cam 17, and the automatic stop referred to is not moved into position to obstruct upward movement of the pressureroller; This mechanism may be briefly described as follows :The lever 102 is pivoted upon the adjacent side frame and has one end overlying the free end of one of the arms 3. As the pressure roller moves down, this lever 102 rocks on its pivot and if the roller is to be held down, a stop is placed under the opposite end of lever 102 so as to prevent turning movement of that lever side-frame. -This stud also carries a pivotedlever 105*" having a roller at its end adapted to coact with a cam 106 on shaft 16. A

spring 107 connects arms 105 and 103?. A rock-shaft 12 extending between the side frames has a lever-18 secured thereon and carrying a roller adapted to ride on the surface of the cam 17 also secured on the shaft 16. Loose on shaft 12 is a lever 111 bifurcated at its end to embrace a pin 112) on the arm 103. The lever 111 has an extension 113 which niay engage'a pin 114 on the side frame to limit the movement of arm 111. A spring 115 acts on lever 111 to turn it in a counter-clockwise direction, (referring to Fig. 1) carrying extension 113 into engagement with a lateral projection 118 of arm 18. A spring 116 acts on arm 18 in a direction to hold its roller in engagement with cam 17. The pin 114 projects inwardly from the adjacent side frame of the machine under the extension 113 of arm with a sheet, the movement -,of these feelers being arrested by a sheet if the latter is in position, but in the absence of such a sheet, being continued to the position in which the feelers are shown ,in Figs. -1 and 1. The rotation of shaft 16 and cam 17 thereon permits shaft 12 to be rocked by spring 116 so as to raise the free ends'of the feelers. If the feelers engage a sheet, the rocking of shaft 12 in its bearings is arrested in. osition where the roller on arm 18 is away rom the periphery of cam 17 At this time the lever 111*.will be held by its spring with' its arm 113 engaging the'projecting end 118 of the arm 18 and the position of arm 111 at'this time is such that the arm 103 is retracted so that its end is out from under the end of lever 102 Consequently the lever 102 can rock on its pivot and allow the pressure roller to be raised in operative position. But if no sheet has been in positionwhen the feelers were raised, the roller on arm 18 would be permitted to follow the contour of cam 17 to theposition in which it is shown in Fig. 1*. As arm 18 moved so its end 118 would depress the extension 113 of arm 111.

102 so that it would obstruct downward movement of this end of lever 102 and hence upward movement of the opposite end of the lever and the'pressure roller. If it should happen that the'movement of arm 103* from its inoperative position to its operative or stopping position shown in Fig. 1 were ob structed by the end of lever 102 because this movement of arm 103 occurred in advance of the upward movement of the adj a cent end of lever 102*, the cam 106 would depress the free end of arm 105 so as tofront of the counter device, which is positioned in a circular opening in one of the side-frames 20 of the machine, as shown in Fig. 2. The device is provided with a main spindle 21 which carries at its front end the knurled head 22 for turning the same and the pointer 23 adapted to -move over the surface of dial 19. The units ratchet wheel 24 is mounted on spindle 21. The

hundreds ratchet wheel 25 is secured to a plate 26, carrying a pointer 27, adapted to be positioned in linewith one of the characters indicating hundreds ondial 19, as

shown in Fig. 3, the plate 26 having a handle 28 extending forwardly beyond the dial, whereby the hundreds ratchet 25 may be set. The plate 26 and ratchet, with the parts moving therewith, are provided with a hub 29 rotatably mounted on the boss 30 of the spider 31, through which' boss extends the spindle 21. The spider 31 is supported in proper posit-ion by pins 32, extending upwardly from the main or base plate 33,

spacers 34 being interposed between spider 31 and base plate 33, and nuts 35 being mounted on the screw-threaded ends of pins 32 to hold the spider 31in position. Base plate 33 is provided w-ith peripheral lugs 36 through which screws pass to secure'plate 33 to lugs on the side-frame 20 of the mahi'ne.

' To set the units pointer 23, the knurled head 22 is moved in a counter clockwise direction as shown Fig. 2, and to set he This would cause the end of arm 103 to be carried under the end of'lever dial 19.

hundreds pointer 27, the handle 28 is also moved in acounter clockwise direction, the indexing ratchet Wheels 24 and 25 being rotated accordingly, reverse movement of these ratchets being prevented by pawls 37 and 38 mounted on pivot pins 39 and 40, on'the rear and front faces of spider 31 respectively, these pawls being pressed by springs 41 and 42 respectively, into contact with their respective ratchet wheels to prevent backward movement thereof.

The units ratchet wheel 24 is provided with a circular index plate 43 on the rear or right side thereof, referring to Figs. 5, 8 and 9, and a corresponding index plate 44 on the left or front side thereof, these plates being provided with notches 45 and 46, respectively. The hundreds ratchet wheel 25 is provided with an index plate 47 on the right or rear side of the said ratchet wheel, referring to Fig. 5, this index plate 47 having a notch 45 in alinement with the notch 45 of the rear index plate 43 of the units ratchet wheel. Tumbler pawls 48 and 49, referring to Figs. 3, 4, 7, 12 and 13, are adapted to ride on the peripheries of index disks47 and 43, respectively, and to drop into the notches in the same when the latter have moved into alinementwith the operative endsof the tu'rnbler pawls, which occurs when th eunits and hundreds pointers are in alinement with the zero of the dial 19. This permits the bell to be rung by mechanism hereinafter to be described, to indicate that the desired number of sheets have been printed. r

The pawls for advancing'the units-and hundreds ratchet wheels respectively, are illustrated at 50 and 51 respectively, Figs. 3, 10 and 11, the hundreds advancing pawl 51 being kept out of engagement with the hundreds ratchet wheel 25 until the completion of one revolutionof the units ratchet wheel, by tumbler pawl 52, mounted integral with a sleeve 53 from which the hundreds advance pawl 51 is also integral, tumbler pawl 52 riding on the periphery of index disk 44, which is secured to the units ratchet 24. When the units ratchet 24 has completed one revolution, pawl 52 drops into notch'46 of index disk 44, permitting pawl 51 to drop into engagement with the hundreds ratchet wheel to advance the same one revolution and thereby move the hundreds pointer one unit to the left on The manner in which the units ratchet wheel 24 is rotated step by step will now be described.

Pawl 50 is integral with-a sleeve 54 loosely mounted on a pin 55, which iXcarried at the end of an arm 56. .Arm 56 is pivotally mounted on its opposite end to the frame plate 33 at the axis thereof, arm 56 being adaptedto oscillate between stop ins 57 57 on plate 33. -Arm 56 is pivoted on a short sleeve extending a short distance through plate 33, this being held in place by the nut 58 threaded on the rearend of the sleeve to the rear of plate 33, this sleeve having a portion 59 ofv enlarged diameter on its inner end, between which and the plate 33 arm 56 is held, so as to'be able to oscillate over the inner or front surface of plate 33. A spring 60 secured to pawl 50 andto'the end of lever 56, as indicated at 61, holds pawl 50 in engagement with units ratchet wheel. '24 to actuate the same.

1' forward or downward oscillation of arm 56,

to advance the hundreds ratchet wheel .one

unit.

The crank 62 has a crank pin .63 pivotally mounted on a lug or extension 64 extending from the lower surface of frame plate 33,

crank 62 carrying a roller 65 on a pin66 at its free end. Crank 62 is preferably formed with a hub 67 which is pinned to crank pin 63 as illustrated in Fig. 5. Crank 62 is mounted on the rear side of lug 64 as illustrated, and roller 65 engages a cam 68 on a shaft 69 of the duplicating machine as shown in Fig. 1. Shaft 69 is continuously rotated during the operation of the machineby gear connection with shaft 16, cam 68, as well as the sheet-feeding sectors 15 of the machine, completing one revolution each rotation of the drum 1. A spiral spring 70 is coiled about the spacer 71 on crank pin 63,. the spring having one end secured to crank 62 and the other end secured to lug 64 on plate 33 as shown in Fig. 5, to hold roller 65 at all times in contact with the surface of cam 68. p

A crank 72 is secured to crank pin 63, on the inner or forward face of lug 64, to oscillate with crank arm 62, its motion being limited by a stop 72 on lug 64. Crank 72 is pivoted at 73 to a lever 74, the upper end of which is pivoted at 75 to a link 76; Link 76 carries at its upper end a pin 77, which extends through a slot-78 in base plate '33,

pin 77 having a boss 78 thereon on the rear surface of plate 33, as shown in Fig. 5. The upper portion of link 76 is thereby caused to slide upon the inner surface of plate 33 when pin 77 is moved iniitsslot .78, link 76 having a forward bend 79 therein to enable the same to clear arm 56. Lever 74 and link 76 are oscillated each rotation of the drum '1 by the" oscillation of crank 62, lever 74 and and link 76 moving as atoggle during such oscillation. Lever 74 has a portion 80 explate 33 according to whether pin 77 is at the upper end or-the lower end of its slot 78 in plate 33. Pin 77 extends intoand is rotatably mounted in the adjacent arm 3, pivotally supporting the pressure-roller 2 of the duplicating machine as shown in Fig.

1. Accordingly, pin 77 and the parts connected thereto constitute the "controlling means for the registering mechanism, the pin rising to the upper portion of its slot, as shown in Figs. 6 and 7, when arms 3 move to their upper position to co5perate with a sheet of paper passing between pressureroller 2 and drum 1, foot portion 80 of lever 74 actuating devices to oscillate arm 56 when the pin is in this position, portion 80 of lever 74 being out of position to contact such actuating devices for arm 56 when the pin 77 is in its lower position. The cam 68 on shaft 69 is so located as to oscillate crank 62 and lever 74 at the moment when .pressure-roller 2 is in its u er osition rovided' that a sheet of paper is passing between the pressure-roller and the drum. As

stated above, arms -3 are prevented from' moving to their upper position at such times if no sheet of paper is being fed forward to printing position, and accordingly at such times the forward oscillation of lever 74 is inefiective to oscillate arm 56.

' A lever or pawl 81 which I term an advance lever is pivotally mounted on a pin 82 carried by an arm 83 of lever 56 depending below the pivotal point ofarm 56. Arm 83 of lever 56 is provided with an upwardly extending stop lug 84 and advance lever 81 has a tail portion 85 adaptedto contact lug 84. A spring 86 is secured to advance lever 81 and to a fixed member 87 which is mounted on base plate 33, the function of spring 86 being to depress advance lever 81, when permitted so to do, into'the position shown in Fig. 6, in which tail 85 of lever 81 contacts lug 84. When the parts are in this position, and pin 77 is in the upper portion of its slot,

the portion 80 of lever 74 contacts advance lever-81 and oscillates levers 81 and 56t0- gether' about the fulcrum of lever 56, the 'units ratchet wheel 24 thereby being advanced oneunit each oscillationof crank 62.

A spring 88 returns lever 56 to its upper position in each forward or downward OSClllation of the same caused by the connections described. a

As stated, the advancing movement of theratchetwheels 24 and 25 should cease when the number of sheets for which the device is set have been printed, at which time tumbler pawls 48 and 49 drop into the notches of the disks'43 and 47 mounted on the rear sides of ratchetwvheels 24. and 25,

Fig. 5. Accordingly, a release pawl 89 is pivotally mounted on the same pin, 90, as the tumbler pawls 48 and 49 referred to. As is shown in Figs. 12and 13, pawls 48 and 49 are mounted to move together, being integral with a hub 91 having. a forwardly extending arm 92 connected by a spring 93 to the fixed member 87, this spring drawing the pawls. 48 and 49 forwardly when theirpointed ends come in line with the notches in the disks 43 and 47 The release lever 89 is mounted between the lower pawl 49 and the base plate 33. Release lever 89 carries a depending arm 94 adapted to engage a lug 95 extending downwardly from pawl 49. A spring 96 connected to release pawl 89 and fixed member 87 tends to move the release pawl '89 downwardly, but this is prevented so long as tumbler pawls 48 and 49'are in contact with the peripheries of disks 43 and 47 by the engagement of portion 94 of the release lever with lug 95 on the tumbler pawl 49. When, however, the tumbler pawls 48 and 49 drop into their notches, release pawl 89 is moved downwardly to contact the tail 85 of advance pawl 81 and move the latter into the position shown in Fig. 7 in which pawl 81 is out of the path of portion 80 of lever 74, pawl 81 also being out of contact with lug 84 on arm 56, so that at this time the oscillation of lever 74 is ineffective to rock .33. A spring 103 is secured to lever 101 and to a lug on the bracket 104 which is secured to frame member 33, the forward or striking movement of lever 101 under the influence of spring 103 being limited by a stop 105. on bracket 104. The bell lever 1.01 is actuated by a trigger 106 pivotally mounted at 107 on a lever 108 pivoted at 109 to frame member 33. Lever 108 is provided with a stop lug 110, and a spring 111 is se-.

' cured to trigger 106 and to a pin 112 on frame plate 33, to hold the trigger against lug 110.

A curved lever 113 is pivotally mounted at 114 to plate 33. This lever has a forward end 115 positioned to be contacted by the forward end 80 of lever 74, each oscillation of the latter, to rock lever 113 about its pivot. Lever 108 has a small projection. 116 on its side adjacent to. lever 113, and in contact with a surface of the latter as shown, so that oscillation of lever 113, each oscillation of crank 62, serves to rock lever 108. The oscillation of lever 108 is not suflicient to operate'bell lever 101 except at such times as tumbler pawls 48 and 49 are in the notches provided therefor in disks 43 and 47 This is provided for by a latch lever 117 pivoted on pm 114 to which lever 113 also is pivoted. Latch lever 117 is spring pressed into its upper position shown in Fig. 6 by a spring 118 secured to the tail of lever 117 and to a pin on frame member 33. Lever 108 is provided with a lug 119 which is adapted to coiiperate with a notch 120 on latch lever 117, when the latter is in its raised position, as shown. in Fig. 6, this latch holding lever 108 so far to the right, as shown in Fig. 6, as to prevent sufficient oscillation of the same, during the oscillation of lever 113, to operate the bell lever. Latch lever 117 is depressed to unlatch lug 119 and lever 108, when pawls 48 and 49 drop into their notches on disks 43 and 47. This is accomplished by a forwardly extending arm 121 of the units tumbler pawl 49, which engages a pin or lug 122 on latch lever 117, when the tumbler pawls 48 and 49 move forward into their respective notches as stated. This swings latch lever 117 in a clockwise direction, against the spring 118, from the position shown in Fig. 6 to that shown in Fig. 7. In the position of the parts shown in Fig. 7, the bell is about to be struck, latch lever 117 having been released, trigger 106 having moved bel lever 101, against the tension of spring 03, into its rear position,

and trigger 106 having moved past the de-, pending short arm of bell lever 101. Spring 103 now causes the bell to be struck and if the machine is continued in operation, the bell will be struck each oscillation of crank .62, the latch lever 117 being held in unlocking position and the ratchet wheels remaining stationary because of the inoperative position of advance lever 81 shown in Fig. 7.

In the assembly of the device, the axle 21 of the'units registering wheel 24 extends through the sleeve 59 and into a bearing therefor in the base plate 33, disk 43 secured to ratchet wheel 24 rotatably resting on the forward surface of sleeve 59. Hundreds ratchetwheel 25, with disk 47 on the under side thereof and member 26 carrying pointer 27 and handle 28 on the upper or forward side thereof, is rotatably mounted as stated on the hub 30 of spider 31. The front of the device is protected by a thin washer 123 of metal, a washer 124 of felt, or the like, and the dial 19 as shown in Fig. 3, the whole device being mounted within a circular opening in the side frame 20 of over the metal washer 123 about the periph ery in the opening of the frame to prevent the entrance of dust.

-It will be noted that in theoperation of the device, the pointers 23 and 27 are set I respectively for the desired number of units and hundreds corresponding to the number of sheets tobe printed, and that as the pointers move in a counter-clockwise direction over the scales on .the dial the number of sheets still to be printed is always indicated, the graduations on the dial progressing in a clockwise direction. When both pointers have returned to the zero of the scale, tumbler pawls 48 and 49 drop into their respective notches in disks 43 and'47 permitting the striking of the bell and rendering theindicator and advancing mechanism ineffective for further movement until paper is positioned between the same to be imprinted, in the regular operation of the machine, means for holding the same apart when no sheet is so positioned, indicator actuating means, a controlling device, automatieally movable in the regular operation of the machine into positions corresponding to the operative and inoperative positions of said printing couple, and connections between said actuating means and a periodically movable element of the machine, controlled as to operativeness by the position of said controlling device, substantially as set forth. c
